Police in North Myrtle Beach and Myrtle Beach arrest four women on prostitution charges in unrelated incidents, according to authorities.

In North Myrtle Beach, police arrested Sang Nim Lee, 54, of Duluth, Ga., and Pyong Un Roy, 53, of Annadale, Va., on charges of business license violation and prostitution, according to records at J. Reuben Long Detention Center. Lee was charged with third or subsequent offense of prostitution, while Roy was charged with second-offense prostitution.

Both women remain jailed after being booked in about 11:30 a.m. Tuesday, according to records.

Lee is being held on $3,315 bond, while Roy’s bond is $1,315.

North Myrtle Beach police arrested the women after they had received several complaints about K-Spa at 807 37th Ave. S., in the city, according to a police report. Officers learned the business owner had a business license, but had a man listed as the licensed massage therapist and not the women.

Undercover detectives went into the business and in the police report they said the women offered to perform sexual acts for money, according to the report. The women had been involved in a similar type of business and arrested in other states.

Roy had been convicted once of prostitution, while Lee had been twice convicted of the charge, according to the report.
